As brightly colored fish dart in and out of the rocks scattered in a small aquarium, a bewildering melody follows each of their movements. The eerie symphony comes from an “audio aquarium,” a contraption dreamed up by Georgia Tech scientists as a way to let blind people experience sea life. The researchers say they wanted to help people with disabilities do something that’s more fun than functional. “Many of the things we do help them solve basic problems — shopping, working, brushing their teeth,” says Bruce Walker, an associate professor who works with the school’s Center for Music Technology.
